Instead of discussions around Vijay's performance or the film's impact, the trailer has become a laughingstock online, thanks to a shockingly careless blunder.

Within seconds of the trailer's release, sharp eyed viewers noticed something unbelievable at around the 23 second mark. A brief shot showing a man with a gun clearly carries a Google Gemini AI watermark, sitting there proudly as if it were part of the film's branding. For a movie of this scale, this is not just a mistake, it is downright embarrassing.

Social media wasted no time tearing into the makers. People are asking how a Rs. 400 crore film, starring one of the biggest stars in Indian cinema, cannot even clear a basic AI watermark before releasing a trailer. This is not some low budget YouTube short or an experimental indie project. This is supposed to be Vijay's send-off film, hyped as a political and cinematic statement.

The bigger joke is that the watermark is still visible many hours later, meaning nobody in the team, not the editor, not the director, not the producers, bothered to double check the final cut. When M9 checked for the same at 12 PM on Sunday, the logo still exists in the trailer.

Many netizens mocked the irony of using AI for a simple gun shot in a remake film, calling it next level laziness. Many pointed out that the makers are trying to sell recycled trash in the name of Jana Nayagan and could not even bother to shoot or polish basic visuals properly.

While a handful of fans tried to defend the use of AI, most audiences were furious. The common sentiment online is simple. If this is the level of attention given to a trailer, what confidence should viewers have in the film itself?

For a film that wants to look massive, polished, and legacy-defining, Jana Nayagan has instead delivered a masterclass in how not to handle post-production. This is not just trolling; it is plain ridicule.
